PRR S1
The PRR S1 class steam locomotive (nicknamed "The Big Engine") was a single experimental duplex locomotive of the Pennsylvania Railroad. It was designed to demonstrate the advantages of duplex drives espoused by Baldwin Chief Engineer Ralph P. Johnson. The streamlined Art Deco styled shell of the locomotive was designed by Raymond Loewy. The S1 had a unique 6-4-4-6 wheel arrangement, meaning that it had two pairs of cylinders, each driving two pairs of driving wheels. To achieve stability at fast passenger train speeds (above 100 mph), articulation was not used. The S1 was completed on January 31, 1939, at Altoona shop, and was numbered 6100. At overall, engine and tender, the S1 was the longest reciprocating steam locomotive ever; it also had the heaviest tender (451,840 lb / 205 tonnes), highest tractive effort () of a passenger steam engine when built and the largest driving wheels (7 feet in diameter) ever used on a locomotive with more than three driving ...

Pennsylvania Railroad
The Pennsylvania Railroad ( reporting mark PRR), legal name as the Pennsylvania Railroad Company, also known as the "Pennsy," was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. At its peak in 1882, the Pennsylvania Railroad was the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Over its existence, Pennsylvania Railroad acquired, merged with, or owned part of at least 800 other rail lines and companies. At the end of 1926, it operated of rail line;This mileage includes companies independently operated. PRR miles of all tracks, which includes first (or main), second, third, fourth, and sidings, totalled 28,040.49 at the end of 1926. in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific and Atchison, Topeka & Santa Fe railroads. Its only formidable rival was the New York Centra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Railroad Class GG1
The Pennsylvania Railroad Class GG1 is a class of streamlined electric locomotives built for the Pennsylvania Railroad (PRR), in the northeastern United States. The class was known for its striking art deco shell, its ability to pull trains at up to 100 mph, and its long operating career of almost 50 years. Between 1934 and 1943, General Electric and the PRR's Altoona Works built 139 GG1s. The GG1 entered service with the PRR in 1935 and later ran on successor railroads Penn Central, Conrail, and Amtrak. The last GG1 was retired by New Jersey Transit in 1983. Most have been scrapped, but sixteen are preserved in museums. Technical information Body and mechanical The GG1 was long and weighed . The frame of the locomotive was in two halves joined with a ball joint, allowing the locomotive to negotiate sharper curves. The body rested on the frame and was clad in welded steel plates. The control cabs were near the center of the locomotive on each side of the main oil-cooled tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRR Q1
The Pennsylvania Railroad class Q1, #6130, was a single experimental steam locomotive designed for dual service. The locomotive entered service in 1942, and retired in 1949 after accumulating a relatively low 165,000 service miles. The Q1 had a 4-6-4-4 wheel arrangement, consisting of a four-wheel leading truck, two sets of driving wheels (six and four) in a rigid locomotive frame, and a four-wheel trailing truck. The first group of six driving wheels were powered by a pair of conventional front-mounted cylinders, while the rear four driving wheels had their cylinders mounted behind them, on either side of the firebox. The driving wheels were , larger than the PRR's existing dual-service locomotives. The Q1's streamlined design consisted of a blunt nosecone in front of the smokebox, extended side skirts covering the locomotive's pipework, and a streamlined shape on the tender similar to the PRR's S1, S2, and T1 passenger locomotives. The cab front was set at a rakish angl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateral Motion Device
A lateral motion device is a mechanism used in some railroad locomotives which permits the axles to move sideways relative to the frame. The device allows easier cornering. Purpose Before the introduction of the lateral motion device, the coupled driving wheels on steam locomotives (often simply called "drivers") were held in a straight line by the locomotive's frame. The flanges of the drivers were spaced a bit closer than the rail gauge, and they could still fit between the rails when tracking through a mild curve. At some degree of curvature, though, the flanges on the center driver would begin to bind in the curve. The closer the front and rear drivers were, the smaller the radius of curve that the locomotive could negotiate. One solution was to make the center driver(s) "blind," i.e. without flanges on the tires. The other solution was to allow at least one of the axles (often the front driver) to move laterally relative to the frame, and such designs incorporated various devi ...

General Steel Castings
General Steel Industries, Inc. (GSI) was an American steel company that operated independently from 1928 to 1981. It was founded by two locomotive manufacturers and a foundry as General Steel Castings Corporation in Eddystone, Pennsylvania. The following year, it acquired the Commonwealth Steel Company, a critical supplier to the rail industry, and the year after that, completed its own modern steel foundry.''The Commonwealther'', August 1929 (Commonwealth Steel Company, 1929), p. 3 In the late 1950s, the company began acquiring other companies in an effort to diversify from its core business of manufacturing large steel castings. By 1971, it had six divisions and one subsidiary.General Steel Industries, Inc., 1971 Annual Report, p. 4 Two years later, it closed its original Castings Division.

Locomotive Bed
A locomotive frame is the structure that forms the backbone of the railway locomotive, giving it strength and supporting the superstructure elements such as a cab, boiler or bodywork. The vast majority of locomotives have had a frame structure of some kind. The frame may in turn be supported by axles directly attached to it, or it may be mounted on bogies (known as trucks in American English), or a combination of the two. The bogies in turn will have frames of their own. Types of frame Preserved GWR 9017 showing outside frames Three main types of frame on steam locomotives may be distinguished:, p 255. Plate frames These used steel plates about thick. They were mainly used in Britain and continental Europe. On most locomotives, the frames would be situated within the driving wheels ("inside frames"), but some classes of an early steam locomotive and diesel shunters were constructed with "outside frames". Some early designs were double framed where the frame consisted of pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baldwin Locomotive Works
The Baldwin Locomotive Works (BLW) was an American manufacturer of railway locomotives from 1825 to 1951. Originally located in Philadelphia, Pennsylvania, it moved to nearby Eddystone, Pennsylvania, Eddystone in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete when demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima Locomotive Works, Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation. The company has no relation to the E.M. Baldwin and Sons of New South Wales, Australia, a builder of small diesel locomotives for sugar cane railroads. History: 19th century Beginning Matthias W.
